BACKGROUND OF THE INVENTION

1. Field of the Invention

Embodiments of this invention relate to systems and methods for makingcement and to cement compositions derived therefrom.

More particularly, embodiments of the present invention relate tosystems and methods for making cement and to cement compositions derivedtherefrom, where the system includes a cement raw material supplysubsystem, a burnable fuel supply subsystem, a cement kiln subsystem,and a cement storage and distribution subsystem. Embodiments of thesystems of this invention integrate a healthcare materials (used orunused) supply and conditioning subsystem into a traditional cementsubsystem so that healthcare materials (used or unused) can be directlyused as a fuel and/or a raw material in the cement production.

2. Description of the Related Art

Cement clinker is produced by feeding a mix of raw materials, such aslimestone and silica-containing materials, into a high temperaturerotating kiln. Generally, crushed raw materials are stored on site at acement plant in raw material storage facilities, such as a raw materialsilo or other suitable storage means. In addition to limestone, rawmaterials may include clay and sand, as well as other sources ofcalcium, silicon, aluminum, iron, and other elements. Raw materialsources may be transported from a nearby quarry or other sources.

The various raw material components are fed by a raw material feederinto a grinding and mixing facility, such as a raw mill. Raw materialcomponents may also be fed directly to a rotating kiln. The finalcomposition of the raw mix depends on the composition and proportion ofthe individual raw material components. The proportion of the rawmaterial components in the raw mix depends on the rate at which eachcomponent is fed into the raw mill or into the kiln.

The raw mix is heated in the rotating kiln, where it becomes partiallymolten and forms clinker minerals, or cement clinker. The cement clinkerthen exits the kiln and is rapidly cooled. The cooler may include agrate that is cooled by forced air, or other suitable heat exchangingmeans.

Clinker kiln dust may be emitted from the kiln and from the cooler,along with exhaust emissions. For example, clinker kiln dust may becomesuspended in the forced air used to cool the clinker exiting the kiln.The forced air may be filtered and reclaimed clinker kiln dust from thefilter may be fed back into the kiln system as a raw material input.

Fuels such as coal and petroleum coke are used to feed the kiln flame toheat the raw mix in the kiln. Other fuels may include whole tires, tirechips, or other alternative fuels such as liquid wastes and plastics andfuels disclosed in co-pending U.S. patent application Ser. No.12/610,331, filed 1 Nov. 2009 (Nov. 1, 2009). Fuels may be stored at thecement plant in fuel storage containers, and fed into a fuel mill via afuel feeder. Gaseous fuels, such as natural gas, may also be used asfuel. Gaseous fuels may be piped to the kiln, and regulated by valves orother suitable flow regulation means. A quality control operatorgenerally monitors the rates at which fuels and raw materials are fed tothe kiln.

The composition and properties of the raw materials and fuels determinethe final composition of the cement clinker, and contribute to theoverall efficiency of the cement system. For example, the raw materialsand fuels each have a certain moisture percentage, indicative of theamount of water present. Further, the raw materials each have anassociated loss factor. The loss factor is indicative of the amount ofwater, CO₂ and organic matter that exits the raw material as it reachesthe high kiln temperatures. Each fuel has an associated heat value andash factor. The heat value is indicative of the amount of heat the fuelwill produce in the kiln. The ash factor is indicative of the amount offuel ash passed through from the fuel to the final cement clinkercomposition.

While many cement plants, systems and methods for making cement havebeen implemented and are currently being developed, there is a need inthe art for cement plants, systems and methods for making cement thatintegrate a subsystem adapted to receive and convert used healthcarematerials into a burnable fuel for cement production.

EXPERIMENTS OF THE INVENTION Example 1

The following data was obtained from a pilot plant facility, where usedor waste material was pre-treated by disinfecting and shredded to formthe particulate burnable fuel of the present invention.

Used or waste material was analyzed based on component makeup. Theanalysis revealed the component ranges set forth in Table I.

Example 2

The following data was obtained from a pilot plant facility, where usedor waste material was disinfected and shredded to form a burnable fueland an ash obtained from burning of other used or waste material wereburned and the resulting ash analyzed.

Disinfected shredded samples were received in 2.5 gallon buckets andwere non-homogeneous at the one gram sub-sample size. Samples wereshredded for particle size reduction. Coarsely milled and finely milledsample splits were returned and showed some inhomogeneity. The morefinely milled sample split was utilized for all analyses.

Due to sample inhomogeneity, all analyses were performed multiple times(duplicate minimum) and values reported as represent “best value”averages. All data were reported on a finely milled sample weight basis.

Samples were stage ashed to 750° C. and held at temperature for 8 hoursfor ash percentage determination. After weighing, ash residues werefused with lithium metaborate for ash component analyses.

Metals except for mercury were determined by ICP-AES and ICP-MS aftertotal sample decomposition with mixed acids including hydrofluoric acidor by high temperature fusion of sample ash with lithium metaborate.Mercury was determined by combustion/amalgamation cold vapor atomicabsorption.

Bromide, chloride, nitrate, sulfate, and ortho-phosphate were measuredby ion chromatography on washings from oxygen bomb combustion, and donot necessarily represent elements in these oxidation states prior tocombustion.

Higher heating value is the gross calorific content and has not beencorrected for possible sulfur content according to ASTM D5865.

The incinerated ash had a BTU/lb value of 5321 (12,377 MJ/kg) resultingin a 49 wt. % residue after burning at 750° C. The resulting ash had anelemental analysis tabulated in TABLE II.
